Embodiment Construction

[0040] In the remainder of the specification and in the claims, in a non-limiting manner and independently of the direction of gravity, the longitudinal direction is oriented from rear to front, the vertical direction is oriented from bottom to top, and the transverse direction is oriented from left to right, Said directions are depicted in the figures as a trihedron "L, V, T".

[0041] In the rest of the description, components having similar, identical or similar functions are denoted with the same reference numerals.

[0042] FIG. 1 shows a front right headlight 20 of a motor vehicle comprising a cover 22 closed longitudinally from the front by a transparent protective outer lens 24 .

[0043] The headlight 20 includes at least one optical assembly 26 disposed within the cover 22 and capable of producing a light beam (not shown) that passes forwardly through the working surface 28 of the refractor 30 along a generally longitudinal optical axis "O".

Abstract

The invention relates to an automobile headlight (10) which has an optical module (26) capable of generating the light beam towards front across an active surface (28) of a refractor (30), and comprises a mask moving between a masking position and an opening position; the mask is interposed longitudinally between the refractor (30) and the exterior lens (24) to partially hide the active surface (28) of the refractor (30) in the masking position. The mask (38) is separated transversally to permit passage of light beam emitted through the surface in opening position.

Description

technical field [0001] The invention relates to a motor vehicle headlight. [0002] In particular the invention relates to a motor vehicle headlight comprising: [0003] shield, closed longitudinally towards the front by a protective external lens; [0004] An optical assembly, arranged inside the shroud, is capable of generating a light beam directed generally longitudinally forward through an active surface of a diopter, for example formed by the front surface of the inner lens. Background technique [0005] Optical assemblies for equipping headlamps of this type are known, and in particular optical assemblies of elliptical shape with a visor making it possible to cut off the light beam. [0006] Elliptical optical assemblies typically include a light source mounted within a generally elliptical shaped concave mirror in such a way that a longitudinal beam is produced by reflection. An internal lens having a front surface forming a refractor is inserted in front of the l...
